Alpha Channel?

I am using GraphicsConverter 4.4 to add an alpha channel to my pictures, but after saving them and then reopening, they appear distorted and the colors very off. What am I doing wrong? Is there any other app that will add an alpha channel?

What format are you saving your files in? Some formats don't support and alpha channel. Also, you might be dealing with a bug. Try opening one of our game asset files with an alpha channel in G.C. Look at the alpha-channel to confirm all is well. Save it in the format you want (and try some others.) This should lead you the issue of what is going wrong.

I have Photoshop Elements but it does not seem to have the ability to save an alpha channel.

I am saving it in TIFF (which I know supports alpha channels). Sometimes it will save the image and alpha channel correctly but other times it won't, which can be very time consuming and frustrating.

In Photoshop (probably in Elements too) you can also create a separate Alpha channel which Photoshop will then save when you save to a compatible format. To create one in Photoshop, click on the "Channels" tab in the layers window. Then in the popup menu select "New Channel" and click "Ok". Now, put all of your alpha stuff in here.
